Hi,

I want to implement an image thumbnail preview control in my application. Wanted to ask whether codejock has any such control ? If yes, my specific requirement is, I want to chnage the preview size of thumbnail at runtime. I will give a slider kind of control to change the preview size (just like Windows Vista Windows Explorer).

So, is this possible with codejock library ? If yes, please let me know from which library version onwards this functionality has been given ?

If you want a good, and simple library for loading images, I would recommend FreeImage - http://freeimage.sourceforge.net/ - http://freeimage.sourceforge.net/
You can use it for free in commercial applications without having to open source your program or pay any royaltees. I use it for loading and displaying images as well as thumbnails (but I also contribute to FreeImage on occasion, so I may be biased).

Hi Ark42,

I want to ask, whether it will work with C# (VS 2005) or not.. !! I dont see this support for C#.. and will it enable me to resize the thumbnail of images at runtime ?

Yes, I believe it works with C#/VB6/Delphi/etc as a DLL at least. I use it statically linked from C++ so I can't really help you with C# or VS2005 problems. There is a function FreeImage_Rescale() which can resize to any size you need quite easily. You might want to take this to the FreeImage forums though, since it's not really related to Codejock anymore.

Hi,

I know its not related to codejock but just want to ask you one thing. I had a look at the site of freeimage library. Its not a control that works like thumbnail control. So, please confirm, will I have to create that control on my own using freeimage ?

Yes, FreeImage is not a control, it is not even Windows-specific - I use it under OS X and Linux as well. It is simply a very simple and easy to use library for loading and saving images in a large variety of formats with some other basic image transformation functions such as resizing.

OK.. so, that will be not useful to me. I saw this is great library, i will surely use it in some of my other projects. Do anybody know any control which can do work for me ? like it shows thumbnail of the image and at runtime, it gives me functionality of resizing them ?

Just write your own. Such a control would not be a complicated thing to create.

@Ark42: Thanks for this freeimage reference. I was looking for something with smaller mem footprint than GDI+ but with the same ease for supporting PNG and JPEG in and out. This is perfect.
